There is no specific sense key information to be reported for the designated

5GPUGNO SENSE￿-G[

%QFG0h

logical unit. This is the case for &GUETKRVKQPa successful command or a command that

 

 

received CHECK CONDITION or COMMAND TERMINATED status because

 

 

one of the following bits is set to 1: File Mark, EOM, or ILI.

 

 

 

 

 

The last command completed successfully with some recovery action per-

RECOV-

 

formed by the drive. Details may be contained in the additional sense bytes

1h

and the Information field. When multiple recovered errors occur during one

EREDERROR

 

command, the choice of which error to report (first, last, most severe, etc.)

 

 

 

 

is device specific.

 

 

 

NOT READY

2h

The logical unit cannot be accessed. Operator intervention may be required

to correct this condition.

 

 

 

 

 

 

 

The command terminated with a non-recovered error condition that was

MEDIUM

3h

probably caused by a flaw in the medium or an error in the recorded data.

ERROR

This sense key can also be returned if the drive is unable to distinguish be-

 

 

 

tween flaw in the medium and a specific hardware failure (Sense Key

 

 

 

HARDWARE

 

The drive detected a non-recoverable hardware failure while performing the

4h

command or during a self-test. The error type could be controller failure, de-

ERROR

 

vice failure, etc.

 

 

 

 

 

 

 

The drive detected an illegal parameter in the Command Descriptor Block or

 

 

in the additional parameters supplied as data for some commands. If the

ILLEGAL

 

drive detects an invalid parameter in the Command Descriptor Block, it ter-

5h

minates the program without altering the medium. If the drive detects an

 

REQUEST

 

invalidTableparameter5-176in the additional parameters supplied as data, the drive

 

 

may have already altered the medium. This sense key may also indicate that

 

 

an invalid IDENTITY message was received.

 

 

 

 

 

The drive generates this sense key whenever the drive is reset by a TARGET

 

 

RESET message, a hard reset condition, or by a power-on reset. Other con-

 

 

ditions that generate a UNIT ATTENTION include:

 

 

The mode parameters in effect for this initiator have been changed by an-

 

 

 

 

other initiator.

UNIT

 

The microcode has been changed.

ATTENTION

6h

Tagged commands queued for this initiator were cleared by another initi-

 

 

ator.

 

 

INQUIRY data has been changed.

 

 

The mode parameters in effect for the initiator have been restored from

 

 

non-volatile memory.

 

 

Other events that require the attention of the initiator.

DATA

7h

A Read or Write command was attempted on a sector that is protected for

PROTECT

this operation. The requested operation was not performed.

 

 

 

 

VENDOR

9h

This sense key is used to report specific Maxtor conditions.

SPECIFIC

 

 

 

 

 

ABORTED

Bh

The drive aborted the command. The initiator may be able to reissue the

COMMAND

command successfully.

 

 

 

 

MISCOM-

Eh

The source data did not match the data read from the medium (i.e., a mis-

PARE

match).
